A model for large-scale volcanic plumes on Io: Implications for eruption rates and interactions between magmas and near-surface volatiles. [PDF]

open access: yes, 2002
Volcanic plumes deposit magmatic pyroclasts and SO2 frost on the surface of Io. We model the plume activity detected by Galileo at the Pillan and Pele sites from 1996 to 1997 assuming that magmatic eruptions incorporate liquid SO2 from near-surface ...

Queen Anne's Wardrobe: Fashion, Sartorial Politics, and the Representational Strategies of the Last Stuart Queen

open access: yesJournal for Eighteenth-Century Studies, EarlyView.
Abstract The final Stuart monarch, Queen Anne, has often been overlooked in studies of visual and material culture, particularly of fashion and dress. This article is the first to undertake a qualitative and quantitative analysis of the wardrobe accounts of Queen Anne, situating her consumption within the context of the eighteenth‐century fashion ...

Research progress of mantle plume

open access: yes地震科学进展, 2021
Since the mantle plume hypothesis was proposed,it has been controversial in academia,and there is no unified answer to its existence. In this paper,the origin of the mantle plume is elaborated in detail.

Mantle heterogeneity during the formation of the North Atlantic Igneous Province: Constraints from trace element and Sr-Nd-Os-O isotope systematics of Baffin Island picrites [PDF]

open access: yes, 2004
Sr-Nd-Os-O isotope and major and trace element data from ~62 Ma picrites from Baffin Island constrain the composition of mantle sources sampled at the inception of North Atlantic Igneous Province (NAIP) magmatism.

Are Mantle Plumes Periodic? [PDF]

open access: yesEos, Transactions American Geophysical Union, 2013
In the past few years, researchers have uncovered evidence that several kinds of geological and biological events seem to show regular cycles of similar lengths. For example, Rohde and Muller [2005] looked at the record of diversity of marine organisms over the past 540 million years and found evidence for two cycles in the data—a roughly 62‐million ...

On Being Receptive: Listening and Compliance on a University Campus

open access: yesAmerican Anthropologist, EarlyView.
ABSTRACT How should you listen when you hear about harms in interpersonal life, such as sexual harassment or anti‐Black racism? Across a range of sites on a university campus, from bystander intervention workshops to reporting systems for sex‐ and gender‐based misconduct, we spotlight the way “listening” is mobilized to address harms of various kinds ...

Large volcanic eruptions are mostly sourced above mobile basal mantle structures

open access: yesCommunications Earth & Environment
Most deep mantle plumes rise from hot basal mantle structures, creating large volcanic eruptions at Earth’s surface. In previous studies, mantle plumes were the implicit process connecting volcanic eruptions to hot basal mantle structures.

Introduction to special section: Hawaii Scientific Drilling Project [PDF]

open access: yes, 1996
Intraplate or "hot spot" volcanic island chains, exemplified by Hawaii, play an important role in plate tectonic theory as reference points for absolute plate motions, but the origin of these volcanoes is not explained by the plate tectonic paradigm ...
